We have performed a set of nonlinear pulsating models for post-AGB stars and have reconstructed the spectral lines for two chemical elements (BaII, CI). The present analysis is devoted to the interpretation of recent spectroscopic observations of the pulsating post-AGB star SAO 96709. We confirm our earlier result (Jeannin et al., 1996A&A...314L...1J) that the dominant pulsation mode is the first overtone and find an increase of the second overtone in the Fourier spectrum with decreasing mass and metallicity Z. The Doppler velocities deduced from the theoretical line profiles vary from 10 to 15 km/s and are in a good agreement with observations. In order to reproduce the observed line broadening, a very large microturbulent velocity has to be introduced, probably with some variations during the pulsational cycle.
